MAINTENANCE

PREPARATIONS
Unless otherwise stated, all service and mainte-
nance must be carried out on a stationary machine
when the engine is not running.
Prevent the machine from rolling by al-
ways applying the parking brake.
Prevent unintentional starting of the
engine by always stopping the engine,
disconnecting the spark plug cable
from the spark plug and earthing it.
Disconnect the negative cable from the
battery.
MAINTENANCE TIPS
To make cleaning and maintenance easier, the cut-
ting deck can be folded up:
1. Set the cutting height setting to an intermediate
position.
2. Undo both pins (fig. 2).
3. Hook the tension pulley arm on the mount.
4. Force the belt off the centre pulley (fig. 7).
5. Grip the deck's frame.
6. Fold up the deck until it is upright on the rear
support plates (fig. 8).
CLEANING
After each use, the underside of the cutting deck
should be rinsed off.
If the grass has dried solid, scrape clean the under-
side.
If necessary, touch up the underside with paint to
prevent corrosion.
POSITIVE DRIVE BELTS
If one of the blades has struck a solid object (e.g. a
stone), the belt tension may be altered. This can
lead to the positive drive belt 'over-meshing'
which, in the long term, can damage the blades.
When replacing positive drive belts, en-
sure that the blades are at right-angles
to each other (see fig. 9).
The working areas of the blades overlap each oth-
er. If the blades' position in relation to each other

has been altered, there is a considerable risk of the
blades striking each other. This can entail serious
damage to the cutting deck.
If this is the case, take the machine and cutting
deck to a service workshop for repair and inspec-
tion.
BLADES
Use protective gloves when changing
blades to avoid cutting yourself.
Ensure that the blades are always sharp. This pro-
duces the best cutting results.
Always check the blades after a collision. If the
blade system has been damaged, defective parts
should be replaced.
Always use genuine spare parts. Non-
genuine spare parts can entail a risk of
injury, even if they fit the machine.
Install the blades according to fig. 15 where the
blade edge is marked. The folded-up edge of the
blade should be positioned inwards towards the
blade holder.
The cutting system comprises two blade bars with
two replaceable blades Y (fig. 10). When replacing
blades, both should be replaced to avoid imbal-
ance.
Install the new blades. Tighten screws V and W
properly. Tightening torque: V - 9.8 Nm, W - 24
Nm.
In the event of a powerful collision, the blades may
be bent out. Undo the locking nut X and fold back
the blade. Install a new genuine break bolt V.
Tighten the locking nuts X and Z.
PIVOT WHEELS
The pivot wheels are equipped with grease nipples
on the pivot axle and the wheel axle. These must
be lubricated after every 50 hours of operation.
